Abstract: PROBLEM TO BE SOLVED: To provide methods and systems for sending multicast messages.SOLUTION: A multicast message having a first format which may correspond to a normal multicast message format is received and transmitted to a plurality of access terminals at a radio access network (RAN). The RAN determines whether the received multicast message requires special handling.

The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the multicast message interpret the message as a multicast message.
